OPTIMAL SEASONAL VOLTAGE CONTROL IN RURAL DISTRIBUTION NETWORKS WITH DISTRIBUTED GENERATORS

Jordan RadosavljeviŠ – Miroljub JevtiŠ – Dardan Klimenta

   This paper proposes a procedure for determining the optimal tap changer positions of off-voltage tap changing transformers in radial rural distribution networks in presence of distributed generators (DGs). The procedure is based on spatial network decomposition and as well as bringing down a branchy LV network to an equivalent line. Optimal voltage module values of PV nodes in the optimal seasonal control plan are determined by the application of a genetic algorithm. The proposed procedure is examined in two real distribution networks: a radial 33-node network with 11~DGs modelled as PQ nodes and a radial 40-node network with three DGs in total, two of which are modelled as PV nodes and one modelled as a PQ node.

Keywords: distribution network, voltage control, distributed generator (DG), off-voltage tap changing transformer (OVTCT), genetic algorithm (GA)
